srncrrrcArron am; part of Lettersi 'atent No. 604,976, dated May 31,I898. Application filed October 9,1897. Berial No. 654,655. (No model.)

To all whom itmay concern:

Be it known that I,-ALAN ROBB FE GUssoN, of Baltimore, in the State ofMaryland, have invented certain new and useful Improvements in Boxes orCans; and I do hereby dcclare the following to be a full, clear, andexact description of the invention, such-as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to an improvement in boxes'or cans for containingand dispensing cheap, and efl'icient device whereby material containedin a box orreceptacle can be measeasily and quickly and without waste.

A further object is to soconstr'uct the valved outlet of a box or can asto keep the same normally'tight.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of v parts,ashereinafter set forth, and pointed out in theclaims.

In the accompanyingdrawings, Figurel is a .view of a can orreceptaclehaving my improvements applied thereto. Fig. '2'is a sectional View.Fig. 3 is a view of amodification.

A represents a box, can, or receptacle for powder or other material,providedat one endwith a fixed cover or top B, having a neck- 0.. Theneck 0 is preferably screw-threaded for the reception of asimilarly-threaded measurer D.' The measurer. D is closed at both endsand provided in its vertical wall with a slot or opening 1. When theineasurer D is. screwed, down, the lower portion of the slot or openingwill communicate with the interior of the body portion of the box orreceptacle, so that powder can flow therefrom into thei'neasurer. Whenthe measurer is in this position, the powder can escape therefrom aboyethe neck.- The powder having been made to enter themeasurer by invertingthe box or receptacle, said measurer willbe unscrewed, so as to cause itto move longitudinally and allow the slot or opening therein to extendabove the upper end of the neck 0. The powder can now be discharged fromthe measurer and communication between the latter and the body of thebox or receptacle will'be closed In the form of the invention shown inFig.

neck and measurer are not screwthreaded, but the measurer is adapted toslide longitudinally, so as to cause the slot or openof the box orreceptacle or to close such communication and discharge the powder intoor onto the device with which it is desired to use it. v

' My improvements are simple in construction, can be manufactured atsmall cost, and are effectual in the performance. of theirfunctions.

Other slight changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting itsscope, and hence I do not wish to limit myself to the precise detailsherein set forth.

Having fullydescribed myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a box or receptacle having a restricted neck,ofa measurer mounted in said neck so as to be capable of longitudinalmovement therein, said measurer bein g hollow and closed at both endsand having a slot in its wall adapted to communicate with the interiorof the box or receptacle and terminate within the neck when saidmeasure'r is closed, and to extend beyond the neck and closecommunication with the interior of the box or receptacle when themeasurer is open, said measurer being constructed to so cooperate withthe neck as to limit the extent of movement of the former in bothdirections.

screw-threaded neck thereon, of a measurer having a corrugated orscrew-threaded wall adapted to mesh with ,the screw-threaded neck, saidmeasurer closed at both ends and having a slot in said corrugated orscrewso proportioned relatively to each other that when the measurer isscrewed outwardly the slot will project beyond the end of the neck andso that when screwed inwardly-the outer end of the slot willbe closedand the inner end be in communication with the interior of thereceptacle, substantially as set forth.
